He1 etoiore, in theoperation ofrakes of the typeindicated, the teeth have beenraised to a predeterminedheight in v order to; discharge; the load, regardless of itssize'o'rheight, from theground, and then the clutch; mecha nism, connecting thebrake: tooth tcflr rying head withthe traction wheels, was automaticallyreleased and theteethipermitted, by gravity, to swing to an operativeposition on the, ground. vAs a result of thismode ot' operation, withthe rake propelled rapidly over the,' round, the teeth would 'fail'z'itoreach an operatiye, position until the rake had passed so far beyond thedischarged load asto leave more or less hayin front of thewindrowunengaged by the teeth. The object'of this invention is toprovidemeans whereby the disengagement of the rake clutchmechanism iscontrolled by the size of the load thatis dumped insucha manner thatwhile the 'raketeeth will swing up to clear a windrow of any size,- theywill always return promptly .to engagement-with the ground afterclearing the same-and therebyrake the hay close to the windrow andincrease the efli'ciency of the rake filIlQlrltS operation.

The lever 12 is provided atits rear end with a loop 22 that slidably receives the rear end of aclutch tripping bar 23, that curves forward and downward substantiallyconcentric with the axis of movement of the rake head, and is pivotallyconnected with a bracket 24 by means of a pin 25, the bracket beingsecured to the draft frame by means of bolts 26. As shown, this bar 23is preferably bent laterally forward of its pivotal connection in orderthat it may extend in front of the seat supporting frame 27, and isprovided with an arm 28 at its front end within convenient reach of theoperators foot in order that it may be readily manipulated. hen theoperator presses downward upon the arm 28 the tripping lever or bar 23at its rear end swings the lever 12 into the position shown in fulllines in Fig. 3, which causes the rock shaft 6 to turn in its bearingsin a manner to shift the clutch engaging members 7 into engagement withthe ratchets 8 upon the traction wheels and cause the rake head to turnabout its axis to dump a load in a well-known manner. As the head rocksforward the loop portion of the lever 12 slides forward upon thetripping bar 23, following its curvature until it contacts with athrow-out that operates to reverse the position of the lever and releasethe clutch mechanism.

In my patent, as noted, when the loop of lever 12 reached the front endof the curved part of the tripping bar 23 and engaged with therelatively horizontally extending member, its movement forward wasarrested and a further angular movement of the rake head in a forwarddirection would cause the lever 12 to disengage the clutch mechanism andpermit the rake head to turn in an opposite direction and carry theteeth to an operative position upon the ground. In dumping the load thepoints of the teeth were always carried to a fixed height, determined bythe position of the throw-out element within the path of the membercontrolling the operation of the clutch mechanism. I am aware that meanshave been provided before my invention whereby the throw-out elementmight be adjusted in a manner to control the degree of angular movementof the rake head in a load dumping direction, but such adjustment wasmore or less permanent in its character and manually controlled. Mypresent invention includes means automatically operative to ad just thethrow-out element according to the height that is necessary to raise thepoints of the rake teeth above the ground to clear loads having variabledimensions without any manipulation on the part of the opera tor. I haveprovided mechanism whereby this result is attained, including a rod 29centrally arranged in the line of draft of the machine, having its frontend turned trans versely, forming a journal portion 30 that is adaptedto rock in a fixed bearing member 31 secured to the draft frame, therearwardly extending body of the rod curving upward and projecting inrear of the rake teeth in the path of the windrow. The journal portion30 of the rod extends beyond the bearing member 31,-and 32 represents anupturned arm thereon, having its upper end turned transversely andpivotally received by an opening in the front end of a longitudinallyextending throw-out member 33, disposed above the tripping bar 23 andparallel therewith, and having secured toits rear end a loop member 34:that slidably receives the bar 23 and permits an upward swing of themember 33 about its axis to a limited extent. with a series of teeth 35upon its upper edge that are adapted to engage with other teeth upon thelower side of the rear end of the throw-out member 33, the angle of thecoacting teeth being such, and the front end of the member 33 beingcarried high enough above the arm 23 to cause the toothed portion of themember 33 to ride over the teeth upon the bar 23 when the member 33 isdrawn forward or pushed rearward by a swinging movement of the arm 32 asthe body of the rod 29 moves upward or downward.

In the operation of the mechanism, when the lever 12 moves forward uponthe bar 23 and the accumulated load is being dumped, its movement isarrested by contact with the rear end of the throw-out member 33, andits direction of movement is such as to prevent the coacting teeth uponthe bar and throw-out member from becoming disengaged. Thus thethrow-out member 33 is in effect held rigid and operates with theassociated parts of the mechanism to disengage the clutch mechanism andpermit the rake teeth to fall to an operative position upon the ground;the po sition of the throw-out member 33 upon the bar 23 determining theeffective height to which the points of the teeth are raised in dumpingthe load, and such position being controlled by an upward swing of therod 29 as it rides over the load of hay being dumped. In other words,the upward swing of the rake teeth is so controlled automati cally thatthe same moves upward just enough to clear the windrow, whatever thesize of the latter, and after they have passed over the windrow, arepermitted to drop down in such a manner as to engage the ground close tothe front of the windrow The bar 23 is provided and to insure eflicientE-raking. j Obviously i)iadaptthcmechanism"shown to use in connectionwith different teams; as, for instance, to teams walking at differentspeeds, thelrod 29gmaybe made adjustable with respecttothe throw-outmember 33 in such avimanner'as to'vary-the amount by which theteethclear the windrow; This may be accomplished, if desired, b ybendingthe-rod at different angles with respect to the ground orby-prov-iding an adjustable connection between the latter and thejournal portion--30, as shown inFig. 5, a collar 36, havingthe front endof the rod 29 seated therein, being wadjustably' mounted on the portion30 as shown; and held in any position';by a set screw 37. v 7
